✦ Synopsis
Tris(n-buty1)phosphine telluride (R,PTe) yields, with HgBr, from acetone solution, a very thermally and air sensitive crystalline solid. This solid has been identified as (HgBr,), . (TePR,),. X-ray diffraction analysis reveals that this compound contains a dimeric cation, [(HgTePR,),BrJ: +, in which each unit is characterized by a six-membered ring made of alternating bonds between mercury and tellurium. The counter ion is a dinuclear anion [Hg2BrJ2-. The crystal belongs to the triclinic system, PT group with a = 12.206(9) A, b = 17.613(10) A, c = 18.065(9) A, and Z = 2. The preparation of this new heterocyclic system and its decomposition under different conditions into Hg,Te$r, or HgTe are presented.
